Guangzhou prediction markets focus on weather forecasting, particularly daily high temperature outcomes. These markets aggregate real-time trader insights on whether Guangzhou's highest temperature will fall within specific ranges—such as 16°C or below, between 17°C and 19°C, or 20°C and above—on any given day. Temperature prediction markets work by allowing traders to express their confidence in specific weather outcomes. As meteorological data, seasonal changes, and long-range forecasts emerge, market prices shift to reflect the collective expectation of thousands of participants. A market price of 75¢ indicates the crowd believes there's roughly a 75% chance of that outcome occurring. Several factors influence prices in Guangzhou weather markets: **Seasonal patterns**: Spring (March–May) and fall (September–November) experience more volatile temperature swings, increasing price movement. Summer months remain consistently hot, making precise predictions more challenging. **Official forecasts**: When meteorological agencies release updated predictions, markets adjust immediately. Forecasts calling for cold fronts or heat waves trigger larger price shifts. **Time of day**: Early-morning prices reflect overnight uncertainty. As local weather stations release observations, traders gain information, and prices stabilize. **Historical patterns**: Guangzhou's subtropical climate shows average highs ranging from 13°C in January to 32°C in July. Traders familiar with typical May temperatures price accordingly. These markets serve as information aggregators for those tracking Guangzhou's climate. Prices reflect the crowd's real-time assessment of temperature outcomes, updated continuously as new data arrives.
